Answer #1

mass of solute (KCl) = 115g

volume of solvent (water) = 750ml

density of solvent (water) = 1.005g/ml

mass of solvent (water) = volume * density = (750ml) * (1.005g/ml) = 753.75g

mass of solution = mass of solute + mass of solvent = 115g + 753.75g =868.75g

PPm = \frac{mass of solute}{mass of solution} X 10^{6}

PPm = \frac{115g}{868.75g} X 10^{6}

PPm = 0.1323741 X 10^{6} PPm

So answer is \left [ 0.1323741 \right ] X \left [ 10 \right ] X \left [ 6 \right ] PPm
